There are way to many options out there is really hard to pick one that works. So anything that you buy without out doing proper research is a bit of a crap shoot. Then on top of all that you have to worry whether its safe to use a product or not. There actually very recently came out an article regarding the FDA labeling some products as unsafe. This is the VigRx FDA safety article just in case you wanted to read that.
Safety tips for pills If you look at all of the different male enhancement reviews out there you will only see them mention all of the good stuff but never any side effects. As a rule of thumb always assume there will be some. Its pretty hard to alter a regular bodies behavior without seeing other things come up. Its a bit like trying to cover a hole on a old pipe. More hole get created after the original one is fixed due to the pressure. Another really important way to stay safe is making sure you aren't using any other medications while you use certain products. Ideally you would want to speak to your doctor of physician before taking anything new. However if the opportunity does not arise or you simple don't feel comfortable talking to them about it don't mix it with other medications or alcohol. I could cause an unsafe imbalance in your body which in some extreme cases can be deadly. The last way of making sure you stay on the safe side of things is making sure you don't take anything on an empty stomach and drink plenty of water. A large part of your body is made out of water. Also some supplements get absorbed better when food is also processing in your stomach. Don't try and be a vigrx rockstar and not follow the rules.
